SASH=FASTENER.

SPECIFIATON forming part of Letters Patent No. 690,440, dated January 7, 1902.

Application filed April 16, 1901. Serial No.'56,092. (No 'model.)

T0 (ZZ whom, it may concern:

, Be it known that I, JOHN A. KEMP, a cit zen of the United States, residing at Fannington Hill, in the county of Tioga, State of Pennsylvania, have invented certain new and useful Improvements in Sash-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relatos to sash-fasteners, and more particularly to the class of mid-rail fasteners and it has for its object to provide a cheap, simple, and efiicient construction the elements of which may be attached to the mid-rails of the upper and lower sashes and which will automatically engage when the sashes are in a closed position.

A further object of the invention is to provide a construction which may be easily and cheaply mannfactured and which will be du rable.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a vertical section through the meetingrails of an upper and a lower sash and through the parts of the fasteningsin their engaged positions. Fig. 2 is a detail perspective view of that member of the fastening having the spring-tongue. Fig. 3 is a perspective view of that member of the fas teningwith which the spring=tongue engages.

Referring now to the drawings, the sashfastening comprises two members, of which one includes a block 5, in which is formed a channel 6 longitudinally thereof, this channel at its upper end having its greatest depth, and its depth gradually decreasing to a point about midway of its ends, after which the depth of the slot increases toward the lower end of the block. It will be noted that this slot extends entirely throu gh the upper end of the block, while it terminates short of the lower end thereof, and that the shape of the slot results in the formation of two upwardly-converging bottom'walls 6 and 7, the adjacent ends of which terminate at the transverse ridge 8, which lies slightly below the front face of the block. At the sides of theslot 6 are the parallel walls 9 and 10.

In the slot of the block 5 and restin g against the lower bottom wall 7 thereof is the lower end portion of a spring-tongue 10, which is riveted or otherwise secured in place, and this tongue extends throughout the length of the slot 6 and projects from the upper end thereof, this projecting portion having a latchshoulder 11 for a purpose which Will be pres ently described. The spring-tongue is continued above the shoulder to form a thu mb= piece 12, which when pressed rearwardly moves the upper portion of the tongue into the upper part of the slot 6 by bending it over the ridge in the slot, so that the outer edge of the shoulder is moved to lic flush with the front edges of the side walls of the slot.

On the meeting-rail 15 of the lower sash is secured thesecond member of the fastening, it being understood thatthe first member described is secured to the meeting-rail of the upper sash, the members being set in recesses in the inner faces of the rails and held by screws passed through perforations therein. The second member consists of a block 16, having a longitudinal channel or slot 17 formed therein, said channel being continued 19 is slanted, so that the channel shoals gradually to the front face of the block.

The two members of the fastening are se cured upon their respective meeting-rails in such positions that if both sashes be raised the second member will lic in the same plano but higher than the first member, and the latching-shoulder of the spring-tongue of the first member will extend into the path of downward movement of the second member. If then the lower sash be drawn downwardly, the latch-shoulder of the spring-tongue will pass into the channel of the block 16 and striking the inclined bottom wall thereof will be pressed rearwardly until the sash is in closed or lowered position, when the springtongue is moved forwardly and snapped over the upper end of the block 16, thus holding the block and therewith the lower sash against upward movement. When the lower sash is to be raised, the thumb-piece of the tongue is pressed rearward] y to carry the latch-shouitending longitudinally thereof to receive the der from the path of the block 16, and the shoulder of the spring-tongue, the bottom of 15 lower sash may be then raised. the channel ofthe second block being slanted What is c1aimed is to engage and press the springtongue rear- 5 The combination with the meeting-rails of ward1y, whereby it may Snap over the upper an upper and alower sash, of fastening memend of the second block. bers comprsing a siotted block having a rib In testimony whereof I hereunto sign my 2o lyng transversely of its slot and a, springname, in the presence of two subscribing wittongue secured to the bottom of the slot at nesses, on the 12th day of March, 1901.
